13 Claims. (Cl. 206-65) This invention relates to improvements in packages for rolls and more particularly to packages of the type in which a plurality of rolls of tape, typically adhesive tape, are carried on a common core.

It is an object of the invention to provide a unitary folding box or carton for packaging adhesive tape rolls or the like, which will hold the rolls safely out of contact with the carton walls under all normal conditions and, hence, protect the same from damage.

Another object of the invention is to provide a tilt top carton of the type indicated, in which damage to the contents in opening the carton is minimized.

An adhesive tape package embodying the invention in a preferred form will now first be described with reference to the accompanying drawing, and the features forming the invention will then be pointed out in the appended claims. t

In the drawing:

Fig. 1 is a flat or plan view of a blank, which is folded to form the carton of the invention;

Fig/2 is an isometric view of the bottom end of the carton, with the end flaps in readiness for folding;

Fig. 3 is a view similar to Fig. 2, showing the flaps partly folded;

Fig. 4 is a view similar to Fig. 2, showing the flaps completely folded;

Fig. 5 is a broken away isometric, showing the inner structure of the carton bottom;

, Fig. 6 is an isometric view showing the upper end of the carton, loaded and with the flaps partly folded;

Fig. 7 is a view similar to Fig. 6, but showing a later stage in the folding of the flaps;

Fig. 8 is an axial section on the line S --8 of Fig. 7; and

Fig. 9 is a side elevation showing the carton opened up for removing the contents.

The carton blank, as shown in Fig. 1, comprises side wall panels 1, 2, 3 and 4 and a glue flap 5 hinged along longitudinal creased fold lines 6 and having top and bottom closure flaps 7-10 and 11-14, respectively, joined to the panels 1 to 4 along transverse creased fold lines 15. Each of the end flaps 7, 9, 11 and 13 carries a marginal projection 20, with rounded end 21, hinged to the end flap on a crease line 22 and having a slit 23 extending into the flap, as shown. The alternate end flaps 8, 10, 12 and 14 are fitted with bifurcated projections 25 having slits 26 and hinged to the end flaps along line 27. Adjacent the line 27, the projections 25 are undercut o1- recessed as at 28 for interlocking as explained below. The end flap panels, in general, have half the width of the wall panels, while end flap extends the full width of the wall panels and carries on a hinge line 30 a fish tail tuck in tab 31, having a notch 32, as shown.

The various wall panels and the glue flap are cut and creased to form a tilt top closure, as follows: back wall panel 4 is formed with a hinge line 35; side wall panels 1 and 3 and glue flap 5 are cut along diagonal lines 36 and 37 to break open, and front wall panel 2 is similarly cut along line 38.

" the same in setting up the top closure.

The blank of Fig. 1 is folded in the usual way on the fold lines between panels 1 and 2 and between panels 3 and 4, glue flap 5 being adhesively joined to panel 1 to form a collapsed carton which is set up and loaded as needed.

Figs. 2-5 show the setting up of the bottom structure, flaps 11 and 13 being first folded over, with projections 2@ turned in, and then flaps 12 and 14 are folded over, the projections 25 being inserted in the slots 23. Shoulders 29 engage under the flaps 11, 13 adjacent the slots, locking the four projections together and forming a strong, solid stud for fitting in a tape roll supporting tube 43, as indicated in Fig. 5.

The carton is loaded with a number of rolls of adhesive tape 41 (Figs. 6, 8 and 9), each having its own core tube 42 and being slid onto a central tube 43 which fits on the bottom stud, formed from the projections 20, 25 as previously explained. The top flaps are now closed, as shown in Figs. 6-8, flaps 7 and 9 being first folded over, tucking their projections 20 into the tube 43 (Fig. 6). Flap 10 is now folded over, the tuck in part being inserted between wall 3 and the edges of flaps 7 and 9, and the projection 25 being bent into the tube 43, the slot 26 straddling the projections 21) of tabs 12 and 14. Following this, the remaining flap is similarly folded over, as indicated in Fig. 8, completing the closure.

The package having the proportions indicated may be about a foot in length, and approximately two pounds of tape may be contained init. As will be apparent, the tape has considerable inertia and holding the tape rolls 41 in a centered position out of contact with the carton walls requires the resistance of considerable inertial forces in shipment. It is found that the projections 20, 25, interfitted together in the manner described, provide a secure anchor for the center tube 43 and hold it in place against all normal stresses encountered in practice. The individual tape rolls 41 may also slide on the tube 43, striking the top and bottom of the closure with considerable force, and it is found that the closure of the invention resists forces of this character also without difficulty.

While the package of the invention may be used with rolls of tape of other types or even with spools of thread, or any of various filaments, the package of the invention is intended primarily for use with adhesive tape which is program wound, or wound under regulated tension, with the result that a roll of a soft consistency and, hence, easily deformed, is provided. It is peculiarly important that rolls of this type should not be subjected to abuse, as they readily become distorted so as to interfere with the unwinding and use of the tape.

As above noted, the tuck in flap 31 is fish tailed, and it will be seen that the leading edges of this flap are located to each side of the carton, so that there is no danger of the flap 31 engaging the tape roll and damaging The cut lines 36, 37 and 38 are also arranged so as to prevent damage to the tape rolls in opening the carton. Thus, each diagonal side out 36 or 37 is cut through almost completely, having perhaps only five or six points of attachment 50, there being only one or two of these throughout the major part of its length and several of them being concentrated adjacent the front of the box, as indicated. Similarly, the front cut 33 has points of attachment 50. adjacent the corners of the box and only a single such point of attachment at its center. in opening the box, pressure is applied with the fingers at the front corners of the box, breaking the attachment at this point and the box top may now be tilted back as shown in Fig. 9, the remaining few points of attachment giving way without difficulty. It is, therefore, unnecessary in opening the box to exert pressure against the center part of the side or front walls where the tape comes close to those walls and, accord ingly, mashing-ofthe-tape-roll 'inopening the carton is prevented. The side walls are preferably inwardly emupon it, or single rolls may be removed without removing the tube 43,as desired, and the top may be reclosed to protect the contents. The hinge line 35 has a certain amount of stiffness, so that unless the cover is held back 'from the solid line position of Fig. 9, it will tend to assume a'position such as shown in dot and dash lines in Fig. 9. In consequence, if the open carton is dropped, the tube 43 and tape rolls 41 will be blocked by the cover, thuspreventing loss of the contents even if an open carton is dropped.

The arrangement of'slotted projections and bifurcated projections 25, provides an exceptionally solid structure, which interlocks, in all directions, as noted above. The rounding off of the ends of the projections, permits making them on such width that their bases may fit the core tube 43 snugly, and still cause no difficulty in assembly and permit reclosing the tilt top as desired. The dimensions of the parts may be varied considerably to suit particular conditions. In general, however, the opening" 26 in the bifurcated projections may be made to fit around the projections 2t) snugly, and the width of the base of the projection 25 between notches 28 may be twice or almost twice the length of a portion of the slot 23 which is cut into the terminal flap '7, etc., so as to obtain a secure interlock in the axial direction.
